Abstract
A hand soap concentrate and a hand soap use solution are provided. The hand soap concentrate is provided with a viscosity of less than about 200 cps. The hand soap concentrate can be mixed with an aqueous solution to provide a use solution having a viscosity of greater than about 1,000 cps. A method for modifying a hand soap concentrate to provide a higher viscosity hand soap use solution is provided. The hand soap concentrate includes a surfactant component for removal of soil, and a component for increasing viscosity with mixing with an aqueous solution.
Claims29
A hand soap concentrate comprising:
- about 14 wt. % to about 24 wt. % anionic surfactant;
- about 1 wt. % to about 10 wt. % nonionic surfactant;
- about 0.25 wt. % to about 5.0 wt. % thickener;
- about 1 wt. % to about 12 wt. % salt;
- about 6 wt. % to about 25 wt. % viscosity builder;
- about 1 wt. % to about 10 wt. % amphoteric surfactant;
- about 2 wt. % to about 12 wt. % humectant;
- and
- about 35 wt. % to about 60 wt. % water;
- wherein the hand soap concentrate exhibits a viscosity of less than about 200 cps.
A hand soap concentrate comprising:
- about 14 wt. % to about 24 wt. % anionic surfactant;
- alkyl polyglucoside having an HLB value of between about 10 and about 14;
- polyethylene glycol distearate having a weight average molecular weight of between about 4,000 and about 8,000;
- about 35 wt. % to about 60 wt. % water to provide the hand soap concentrate with a viscosity of less than about 200 cps;
- and
- wherein the weight ratio of alkyl polyglucoside to polyethylene glycol distearate is between about 3:1 and about 4:1.
A method for modifying a hand soap concentrate to provide a higher viscosity hand soap use solution, the method comprising steps of:
- (a) mixing a hand soap concentrate having a viscosity of less than about 200 cps with water to provide a hand soap use solution having a viscosity of greater than about 1,000 cps, said hand soap concentrate comprising:
- about 14 wt. % to about 24 wt. % anionic surfactant;
- about 1 wt. % to about 10 wt. % nonionic surfactant;
- about 0.25 wt. % to about 5.0 wt. % thickener,
- about 1 wt. % to about 12 wt. % salt;
- about 6 wt. % to about 25 wt. % viscosity builder;
- about 1 wt. % to about 10 wt. % amphoteric surfactant;
- about 2 wt. % to about 12 wt. % humectant;
- and
- about 35 wt. % to about 60 wt. % water.
A method for modifying a hand soap concentrate to provide a higher viscosity hand soap use solution, the method comprising steps of:
- (a) mixing a hand soap concentrate having a viscosity of less than about 200 cps with water to provide a hand soap use solution having a viscosity of greater than about 1,000 cps, said hand soap concentrate comprising:
- about 14 wt. % to about 24 wt. % anionic surfactant;
- alkyl polyglucoside having a HLB value of between about 10 and about 14;
- polyethylene glycol distearate having a weight average molecular weight of between about 4,000 and about 8,000;
- about 35 wt. % to about 60 wt. % water;
- and
- wherein the ratio of alkyl polyglucoside to polyether glycol distearate is between about 3:1 and about 4:1.
